[Constitution Day]

FYI...for your list?

A child's clubhouse, built about 25 years ago by a civil engineer for his son, provides another clue pointing to possible design or construction flaws in the structural failures that breached two canal floodwalls and inundated the city during Hurricane Katrina.

Thanks for the ping, CD.

I have been involved in levee strengthening projets on the American River, specifically in Sacramento where a backhoe digs a trench approx 3-4 wide, and almost 100 feet deep. The trench is backfilled with a soil/cement/bentonite tokeep the water on the proper side. Here's a backhow used in the project. BTW, this work runs about 3-5 million per mile of levee.
